(d) Galaxies

• very far from earth

• relatively close to earth

• Luminous

• can be bigger than earth but not bigger than the sun

• Appear to twinkle and appear white

• non-luminous but we can see it because it reflects light from the sun

• ours is called the milky way

• Is a natural type of satellite

• Found everywhere in the sky

• don't twinkle and can be coloured

• very large, some are bigger than the sun

• Occur along the sun's pathway

• non-luminous

• appears as a hazy band of white light

• large collections of stars, dust, gas and planets

• always very hot

• appears big and bright due to its proximity (closeness) to earth

• contains 200 billion stars

Match the following

• Precession

• the time of year when the hours of daylight equal the hours of darkness

• Solstice

• the force of attraction between all masses in the Universe. The greater the mass of an object, the stronger its gravitational force

• Eclipses

• the changing direction of Earth’s axis. Similar to a spinning top

• Gravitational Force

• an astronomical event that occurs two times each year, when the tilt of Earth’s axis is most inclined toward or away from the Sun, causing the position of the Sun in the sky to appear to reach its northernmost or southernmost extreme 

Match the following

• Rotation

• This means to travel all the way around another object.

• Revolution

• 24hrs or 1 day

• Orbital radius

• 365 days or 1 year

• Earth's rotation

• This means to spin.

• Earth's revolution

• the average distance between an object in the Solar System and the Sun

The earth is closest to the sun around (hint: what month and day):

The earth is farthest to the sun around (hint: what month and day):
